WEBVTT 00:00:05.140 --> 00:00:10.540 We have a new block that's called the if/else block. It's a conditional statement just like 00:00:10.540 --> 00:00:15.719 the if block you've used in the puzzles before. But now there's a new part at the bottom that 00:00:15.719 --> 00:00:22.960 says else. The if/else block lets the bee make a decision between two sets of actions. 00:00:22.960 --> 00:00:27.619 If the bee is at a flower, the bee will do the set of actions you put in the first part 00:00:27.619 --> 00:00:33.870 where it says do. If the bee is not at a flower, the bee will do the set of actions you put 00:00:33.870 --> 00:00:41.910 in the slot where it says else. If statements are how computers are able to make decisions. 00:00:41.910 --> 00:00:46.809 Humans set up conditions for the computer that say if the computer is presented with 00:00:46.809 --> 00:00:55.420 a certain situation do this. Else, which just means otherwise, do that. The top of our if/else 00:00:55.420 --> 00:01:01.620 block says if at flower. But the top of our block could say other things, like if nectar 00:01:01.620 --> 00:01:08.480 equals 2 or if there's a path ahead, our block will behave in the same way. That if the statement 00:01:08.480 --> 00:01:13.450 at the top is true it will do the first set of actions. But if the statement at the top 00:01:13.450 --> 00:01:16.429 is false, it will do the second set of actions.
